Abstract

PURPOSE: To enable a bright display through an ordinary liquid crystal panel by showing the images on two liquid crystal display panels with a shift of a single field secured between them by means of a V start signal using the vertical synchronizing signal of a video signal.
CONSTITUTION: The input conditions of an AND gate 19 are satisfied and an R-V start signal 20a is generated as long as a digital signal (E/O signal) 16a and a pulse signal (VD signal) 18a are identical with the positive signals of the same level. The signal 20a is inputted to a liquid crystal display panel 22R. Meanwhile the input conditions of an AND gate 21 are satisfied and an L-V start signal 21a is generated as long as the signal obtained from the signal 16a via an NOR gate 20 and the signal 18a are identical with the positive signals of the same level. The signal 20a is generated at the time of an EVEN field, and the signal 21a is generated at the time of an ODD field respectively. Thus the liquid crystal display panels 22L and 22R are alternately reset synchronously with a vertical synchronizing signal.
